MANZANITA – Unity by the Pacific in Manzanita is offering a program called “4-T,” which the Rev. Kathleen McKevitt describes as a course in commitment. The church will refund the course fee of $39.50 if those attending are unsatisfied after the 12-week course. McKevitt will share a promotional video and a message at the 10:30 a.m. Sunday gathering of Unity by the Pacific at the Pine Grove Community House, 225 Laneda Ave. The “4-T” class meets weekly, beginning Sept. 29.
